Get the b all alone on one side of the inequality. To do this, we can divide both sides by 5.
5b / 5 ≤ -15 / 5
b ≤ -3
So, that means b has to be less than or equal to -3.
In interval notation it would look like [-3, -∞)
In a set builder notation: {x | x ∈ R, x ≤ -3}
Which is read as the set of all x, such that, x is a member of the real numbers and x is less than or equal to -3.
Answer
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
3 miles ÷ 2
2 hours ÷ 2
=
1.5 miles
1 hour
=
1.5 miles
hour
= 1.5 miles per hour
The number of pages which Claire should read each day to finish the 35 pages in 6 days is; 5.833 pages per day.
<h3>How many pages should Claire read per day?</h3>
It follows from the task content that the number of pages which Claire should read per day in a bid to finish all 35 pages in 6 days be determined.
Since the given condition is such that; Claire reads an equal number of pages on each of the next six days.
It follows that the number of pages to be read each day is given by;
35 / 6
= 5.833 pages per day.
Ultimately, the number of pages Claire should read per day over the next 6 days is; 5.833 pages per day.
